graphicspdfspacing
I create a diagram in Visio and save as a pdf file. There is a large space between the text and the figure, as shown the following:
If I understand well, the problem can be boiled down: how to save a diagram as a pdf file with zero margin (top, bottom, left, right) in Visio.
PS: for the last spacing issue, add \usepackage{caption}.
You can use the commandline tool pdfcrop. For this you need perl.
memoir provides its own interface for caption management, and there may be some clashes when using it in conjunction with caption (see section 10.13 The class versus the caption package (and its friends), p 206 of the memoir user manual).
However, you can update \caption to grab its contents, evaluate whether the argument is empty/not, and condition accordingly:
\documentclass{memoir}
\usepackage{mwe} % for dummy images
\usepackage[labelformat=empty]{caption} % remove figure captions
% http://tex.stackexchange.com/a/58638/5764
\makeatletter
\def\ifemptyarg#1{%
\if\relax\detokenize{#1}\relax % H. Oberdiek
\expandafter\@firstoftwo
\else
\expandafter\@secondoftwo
\fi}
\makeatother
\let\oldcaption\caption
\AtBeginDocument{%
\renewcommand{\caption}[2][]{%
\ifemptyarg{#2}{}{\oldcaption[#1]{#2}}%
}%
}
\begin{document}
\begin{figure}[!ht]
\centering
\includegraphics[width=0.5\textwidth]{image}
\caption{}
\end{figure}
This is first text after caption.
\newpage
\begin{figure}[!ht]
\centering
\includegraphics[width=0.5\textwidth]{image}
\caption{Some caption}
\end{figure}
This is first text after caption.
\end{document}
If you're not using the optional argument of \caption in your workflow, then the redefinition could be a bit simpler:
\AtBeginDocument{%
\renewcommand{\caption}[1]{%
\ifemptyarg{#1}{}{\oldcaption{#1}}%
}%
}

You can remove white margins from a pdf file with
pdfcrop, in the simplest versionwhich generates a maximally cropped output file named
file-crop.pdf. You can also specify new own margins in points (default is zero), and name your output file as you want, as in
